The Stanford Prison Experiment03:20

The Stanford Prison Experiment

23.9K
The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

Reliability and Validity01:29

Reliability and Validity

13.3K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Longitudinal Research02:20

Longitudinal Research

12.8K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Calibration Curves: Linear Least Squares01:20

Calibration Curves: Linear Least Squares

3.3K
A calibration curve is a plot of the instrument's response against a series of known concentrations of a substance. This curve is used to set the instrument response levels, using the substance and its concentrations as standards. Alternatively, or additionally, an equation is fitted to the calibration curve plot and subsequently used to calculate the unknown concentrations of other samples reliably.
For data that follow a straight line, the standard method for fitting is the linear...

Longitudinal Studies

294
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Systematic Error: Methodological and Sampling Errors01:15

Systematic Error: Methodological and Sampling Errors

5.3K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Area of Science:

  • Psychology
  • Forensic Psychology
  • Psychometrics

Background:

  • The Levenson Self-Report Psychopathy Scale (LSRP) has limitations.
  • The Expanded-Levenson Self-Report Psychopathy Scale (E-LSRP) was developed to enhance psychometric properties.

Purpose of the Study:

  • To investigate the construct validity of the E-LSRP.
  • To evaluate the E-LSRP's reliability and validity in a male inmate population.

Main Methods:

  • Confirmatory factor analysis was used to assess the scale's factor structure.
  • Correlational and multiple regression analyses examined convergent and discriminant validity.

Main Results:

  • Confirmatory factor analysis supported a three-factor model for the E-LSRP.
  • E-LSRP scores demonstrated good reliability and construct validity.
  • Evidence supported convergent and discriminant validity against related personality traits and internalizing disorders.

Conclusions:

  • The E-LSRP is a reliable and valid measure of psychopathy in correctional settings.
  • The E-LSRP can be a valuable tool for assessing psychopathy in forensic populations.
